JACK-SPOOL.

To all 'whom it may concern:

Be it known that I, JOHN C. HEBBEN, a

-.citizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, have invented eertain new anduseful Improvements in Jack- Spools, of which the following is aspecification.

My invention consists of improvements in jack-spools or dresser-spoolsemployed in handling warp or filling yarns.

The object of my improvement is to proy rial can be shipped in the formof a package without the spool. v

With this object in view I provide the spool with a detachable barrelwhich serves as a core for the yarn mass. The barrel, preferably in theform of a tube, is held on a central support or stringer havingdetachable end flanges or heads which can be removed to allow theremoval of the barrel and package of yarn wound thereon;

The invention is fully set forth in the following specication,illustrated by the ac companying drawings, in which Figure l is alongitudinal sectional View of my improved spool with the yarn massrepresented by dotanddash lines; Fig. 2, a l

perspective view showing the tubular barrel mounted on the centralsupport or Stringer; 35'

Figs. 8 and 4l, detail views showing a modification in the method ofsecuring the end flanges or heads to the Stringer; Fig. 5, a detail viewsho-wing another method of securing the heads; Figs. 6 and 7, detailviews showing a still further modication.

In Fig. 1, b represents a tubular barrel `supported on the Stringer` c.between the.

heads or end flanges f, j.I The Stringer c is preferably constructed ofangle-iron, as shown more clearly in Fig; 2, thus givmg a three-pointbearing within the tube b. The

tube b may be of metal, wood, paper or fiber v and preferably this lastnamed material is used to provide the required stiffness with minimumweight.

At both ends of the stringeroa metal blocks e, e fitted to thei V-shapedtrough of theangle-iron and se-I cured in position by screws, pins orother suitable fastening means. Secured in the blocks e, e, andprojecting therefrom are studs d, ri, located centrally of -the apex andedges of the angle-iron and adapted to serve as gudgeons for supportingthe spool to rotate in bearings on the winding o-r other machine. Thestuds d, d are here shown as screwed into the blocks e, e and thechecknuts n. g are screwed on to their inner ends against the innerfaces of the blocks to secure them against turning when the spoolrotates in its bearings. At t-he ends of the spool I provide thedetachable heads or flanges f, f bored to fit the studs d, d. Theflanges f, f abut the ends of the Stringery c and ar'e arranged tobeheld in place by any suitable means such as now described: In Fig. 1,the flanges are shown as formed with bosses or hubs f', f and pins it,are driven thro'u h holes in the bosses and registering holes 1n thestuds to hold the flanges against the blocks e, e.

In Figs. 3 and 4 the bore of the flange f is shown as threaded to screwon to the threaded shank cl of the st-ud al. With this l,

arrangement a set-screw j is screwed through the flange with its endabutting the edge of t-he block e to from unscrewing.

In Fig. 5 t-he flange f is shown as secured by a set-screw screwed downthrough the hub of the flange to bind on the stud d.

Figs/6 and 7 show still another method of fastening the flanges inposition at the ends ofthe spool. In this modification each flange isprovided with a button-hold or opening which consists of a slot l' andan enlarged orifice l. A screw n is screwed into the block e in positionto adapt its head 4 to pass through the orifice l.

The flange is then turned to engage the shank of the .screw with theslotZ and the head of the screw is set up against t-he face of the flan e tobind thelatter against the end 'of t e Stringer and hold it fromturning.

The method of operation of my new device is .as follows: The spool isassembled with the tube or barrel b held on the Stringer c between theend Aflanges f, f. The threepoint bearing of the Stringer within thetube centrali'zes the latter in respect to the gudgeons d, d, so that itisconcentric to the axis of the spool and the flanges are securedprevent the flange.

on the gudgeons in any suitable manner as previously described. TheSpool is then applied to the winding machine and the yarn wound on tothe barrel in multiple to build up a cylindrical mass between theflanges or heads. After the Spool is filled it is taken from the windingmachine and one of the end flanges is removed.v The barrel l) is thenItaken ofl'the Stringer and the yarn is supported solely by this barrelor tube b so that the packages of yarn can be packed and shipped in thisform and the Spool proper, consisting of the Stringer and heads, isretained for further use in winding up more material. Heretofore it hasbeen the usual practice to ship the yarn on the complete j ack-spoolsand the spools are returned when emptied. This necessitates payingfreight and cartage on the spools andthe use of the spools is lostduring the time that they are in transit. With this practice the yarnmill must have a great ma'ny more spools than are necessary for use inwinding up the material and as the spools are sometimes lost or damagedin shipment the practice is far from economical. By the use of mypresent invention it is necessary to have only one set of spools at theproducing mill and one set at the converting mill and these spools arekept constantly in use without loss of time in transit and the cost offreight and cartage is saved.

In Some cases it iS desirable to wind the yarn in separate packages onone Spool, so that the whole mass can be divided into relatively smallunits. To provide for this, the barrel can be made up of a plurality ofsections or relatively short tubes m, m, etc., as illustrated in Fig. 2.These Sections are assembled on the Stringer c in the same manner aswith the Single tube and their ends abut each other to form onecontinuous barrel for the spool. The yarn is wound on this form of spoolwith one or more ends built up on each tube Section and the ends of theindividual packages abut each other in close contact so that there isone continuous, cylindrical mass of yarn on the spool. When the endflange is detached from the spool the Separate packages are taken olfthe Stringer and can be handled and packed more conveniently than wherethe yarn is supported on one long tube. This method of spooling the yarnalso provides forapplying the individual packages to different uses andhence does not restrict it to use on a spool of definite length;

It will be observed that my improvedy spool provides for handling warpand filling yarns with greater convenience than when the material iswound on the usual form of jackor dresser-Spool and, furthermore, itsuse results in important economies in Shipment. The yarn can be wound upin package form on the Spool, either in one continuous package or inSeveral shorter ones, and then removed from the spool without unwindingor disturbing the integrity of the yarn mass in any Way. The packagesofyarn can be handled and shipped without the spool much more convenientlyand economically and a less number of spools is required inmanufacturing and converting the material. Furthermore, where the yarnon the spool can be broken up into component packages or units it isrendered more adaptable to diversified uses and can be applied to theprocesses of manufacture more economically.

It will be evident that various modifications might be made in thestructure and arrangement of myimproved device without departing fromthe spirit and Scope of the invention;

Therefore, without limiting myself to the precise construction shown anddescribed, what I claim is z- 1 1.
